It's Punch-Up Night In Canada
While there’s not an explicit wage bonus for fighting, good fighters tend to be paid roughly $18,000 more per fight than non-fighters;
This is even higher than the observed wage bonus for good goal-scorers.
So if you want to dissuade hockey players from fighting, you’ll need to fine them at least $18,000 per fight. Or encourage them to take up curling.
